This will enable staff to arrange another date and time for you and to give your appointment to someone else. If you need travel information, please refer to the Trust website at or telephone us on the numbers above and we will send you an information sheet. 3

4 Introduction You have been advised by your GP or hospital doctor to have a combined gastroscopy and flexible sigmoidoscopy examination. We will need to have your formal consent before we can carry out this examination. This booklet explains how the examination is carried out and what the risks are. This will help you to make an informed decision when agreeing to the examination and whether you wish to have a sedative. The consent form is at the front of the booklet. If there is anything you do not understand, or anything you wish to discuss further, but still wish to come for the appointment, do not sign the consent form. Instead, bring it with you and you can sign it after you have spoken to the endoscopist. The consent form is a legal document please read it carefully. Once you have read and understood all the information, including the risk of complications, and you agree to undergo the examination, please sign and date the consent form. You will notice that the consent form is carbonised, allowing you to keep a copy for your records. Please remember to bring the consent form to your appointment. What is a combined gastroscopy and flexible sigmoidoscopy? You will be having two examinations. The first examination is called an oesophago-gastro-duodenoscopy (OGD), sometimes known more simply as a gastroscopy or endoscopy. The second examination you will be having is called a flexible sigmoidoscopy. Both examinations will be carried out by (or under the supervision of) a specially trained doctor or nurse called an endoscopist. You can choose whether you want to be given a sedative to help you relax. 4

5 What is a gastroscopy? This is an examination of your oesophagus (the tube that carries food from your mouth to your stomach), stomach and duodenum (the first part of your small bowel) using a tube which is passed gently down your throat. The instrument used is called a gastroscope (scope) and it is flexible. The scope has a light which is shone onto the lining of your gut. It also has a very small camera which sends a live image to a screen where it is viewed by the endoscopist. During the examination the endoscopist may need to take some small tissue samples, called biopsies; this is painless. The samples will be looked at under a microscope in our laboratories. The tissue sample and associated clinical information will be kept and may be used for teaching purposes and for research aimed at improving diagnosis and treatment of gastrointestinal diseases. This may benefit other patients in the future. If you do not wish us to keep the tissue sample for this purpose or have any questions or concerns, please tell the endoscopist before signing the consent form. Images from the gastroscopy will be kept in your health record. Why do I need a gastroscopy? You have been advised to have a gastroscopy to try and find the cause of your symptoms. The results will help us to decide on the best treatment for your problem or whether we need to carry out any further examinations. A gastroscopy may be advised for a number of reasons including: indigestion, anaemia, losing weight without trying to, vomiting, blood in your stools, passing black stools, vomiting blood, difficulty swallowing, abdominal pain or a lump in your upper abdomen. 5

6 What are the alternatives? A barium meal X-ray examination is an alternative examination to a gastroscopy. It does not give us as much information as a gastroscopy and has the added disadvantage that tissue samples cannot be taken. If you would like to discuss this option, please speak to your doctor. What is a flexible sigmoidoscopy? This examination is a very accurate way of looking at the lining of the left side of your large bowel (colon) using a tube which is passed gently into your rectum. The instrument used is called a flexible sigmoidoscope and is similar to the scope used for the gastroscopy. The endoscopist may also take small tissue samples (biopsies) from your bowel, as described on page 5. Why do I need a flexible sigmoidoscopy? You have been advised to have a flexible sigmoidoscopy to help find the cause of your symptoms. The results will help us to decide on the best treatment for your problem and whether we need to carry out any further examinations. The reasons for this examination may include: bleeding from the back passage abdominal pain and diagnosing the extent of some inflammatory bowel disease follow-up inspection of previous disease assessing the clinical importance of abnormalities found on X-rays. 6

7 Are there any alternatives? No. Rigid sigmoidoscopy does not reach the appropriate part of the bowel and any other investigations do not allow the tiny biopsies to be taken that help to make a precise diagnosis. What are the risks? Gastroscopy and flexible sigmoidoscopy are simple and safe examinations for most people, but life threatening complications are possible. Serious problems are rare. However, you need to weigh up the benefits against the risks of having the procedure. There can be risks from having the examination itself, as well as from the sedation. The main risks are: A tear (perforation) in the lining of the stomach or oesophagus. This happens to approximately 1 in 2,000 people. This may be treated with antibiotics and intravenous fluids, or may need surgery to repair the hole. A tear (perforation) in the lining of the large bowel. This happens to approximately 1 in 15,000 people. The risk of a tear is higher with polyp removal. If we know before your flexible sigmoidoscopy that you have a large or difficult to remove polyp, your endoscopist will discuss the risks with you in more detail. An operation may be required to repair the tear if it cannot be closed during the sigmoidoscopy. Risk of a missed lesion although gastroscopy and flexible sigmoidoscopy have been selected as the best tests to diagnose your symptoms, no test is perfect. There is a small risk (1 in 100) that we might miss a large polyp or other important finding during your test. Bleeding where we take a sample (biopsy) or have removed a polyp happens to about 1 in 150 people, but this is usually minor and stops on its own. Short term problems with breathing, heart rate and blood 7

8 pressure (related to sedation). We will monitor you carefully so that if any problems do occur they can be treated quickly. Older people and those with significant health problems (for example, people with significant breathing difficulties) may be at higher risk. Damage caused by the endoscope to teeth or bridgework this is very rare. Heart attack or stroke (related to sedation) though this is very rare. Sedation or throat spray? A sedative injection can help you to relax during the gastroscopy if you are anxious. Local anaesthetic throat spray can improve your comfort during the examination. You will be offered the choice of sedation or local anaesthetic throat spray. Flexible sigmoidoscopy is generally performed without sedation, but can be given if you want it. If you find the procedure particularly uncomfortable, we may be able to give you Entonox (gas and air). This should work quickly to reduce any pain. After using Entonox you will need to rest in the department for minutes, until its effects have worn off. If you feel able to, you will be allowed to drive, as long as you have had no other sedation. If you have sedation you must have someone to collect you and drive you home. Sedation The sedative is injected into a vein in your hand or arm and will make you lightly drowsy and relaxed, but will not put you to sleep. You are likely to be aware of what is going on around you and will be able to follow simple instructions during the examination. We will monitor your breathing and heart rate throughout the examination. 8

9 If you have sedation you will not be allowed to drive home. You should also not go home alone on public transport. You must arrange for a family member or friend to collect you. The nurse will need to be given their telephone number so that we can contact them when you are ready to go home. As the sedation can make you drowsy and unsteady on your feet, we also recommend that you have someone responsible to stay with you overnight after the procedure. Anaesthetic throat spray This spray numbs your throat with a local anaesthetic this has an effect very much like a dental injection. As gastroscopes have become thinner, many people are happy for the examination to be carried out without sedation and to have throat spray instead. The benefit of choosing throat spray is that you will remain fully conscious and aware, and can go home unaccompanied soon after the examination (as long as you haven t had Entonox). You will be allowed to drive and can carry on life as normal. The only constraint is that you must not have anything to eat or drink for about an hour after the examination, until the sensation in your mouth and throat has returned to normal. It is strongly advised that when having your first drink after the examination, it should be a cold drink and should be sipped to make sure you do not choke. Preparation Eating and drinking You must not eat anything for at least six hours before your gastroscopy. This is because food can stop the endoscopist getting a clear view of the inside of your stomach. It also increases the risk of inhaling (breathing in) the contents of your stomach into your lungs, which can cause severe pneumonia. You can have sips of water up to two hours before your test. If you do eat something, your test will need to be cancelled. 9

10 Bowel preparation instructions In order to be able to clearly see your bowel, it must be clean. When you arrive in the Endoscopy Unit you will usually be given an enema to make you go to the toilet. Sometimes you will be sent an enema to self-administer at home. If you have been sent an enema please administer it to yourself at home one hour before your appointment. To use the enema, lie down on one side, remove the cap and insert the full length of the nozzle into your back passage. Gently squeeze the tube until it is empty. Keep squeezing the tube as you pull the nozzle out of your back passage. This should not be painful; if you feel any resistance or pain, do not continue. Stay lying down on your side whilst you wait for the enema to work; this will usually take 2-5 minutes. Please refer to the enclosed leaflet for additional information about the enema. What do I need to bring with me? Please bring with you a dressing gown and a pair of slippers. Please leave all valuables at home. The hospital cannot accept responsibility for these items. What about my medicines? You should continue to take your routine medicines with the following exceptions: If you are taking iron tablets you must stop these one week before your appointment. If you are taking stool bulking agents (e.g. Fibogel, Regulan, Proctofibe), loperamide (Imodium), lomotil or codeine phosphate, you must stop these four days before your appointment. Patients with diabetes If you have diabetes controlled by insulin or tablets, please make sure you tell us so that we can give you an appointment at the 10

11 beginning of the morning or afternoon. Please also telephone the Endoscopy Unit at least one week before your endoscopy appointment for advice about your diabetic medicines. Anticoagulants Please telephone the Endoscopy Unit at least two weeks before your appointment if you are taking anticoagulants, e.g. warfarin, clopidrogel, dabigatran, rivaroxiban or apixaban. How long will I be in the endoscopy department? This depends upon whether you have sedation and also how busy the department is. You should expect to be in the department for, most of the morning or afternoon. The department also deals with emergencies which can take priority over outpatient appointments. However, we will try to keep any delays to a minimum. What happens when I arrive at the Endoscopy Unit? Soon after you arrive, you will be reviewed or seen by a nurse who will ask you a few questions about your medical condition and any past surgery or illness you have had. This is to confirm that you are fit enough to undergo the examination. The nurse will record your heart rate, blood pressure and oxygen levels. If you are diabetic, your blood glucose level will also be recorded. The nurse will also make sure you understand the examination and you will be able to ask any further questions or raise any concerns you may have. The nurse will ask you for your signed consent form. If you have not already signed the consent form the endoscopist will be able to answer any questions you still have or talk to you about any concerns. 11

12 The nurse will also ask you about your arrangements for getting home after your gastroscopy and flexible sigmoidoscopy. If you have decided to have a sedative, you must be accompanied home. (See page 9) The nurse will ask you to change into a hospital gown, your dressing gown and slippers. If you have not carried out an enema at home you will be given one now, to help you to clear your bowels. What happens during the examination? Gastroscopy You will be escorted into the examination room where the endoscopist and the nurses will introduce themselves and you will have the opportunity to ask any final questions. If you are having local anaesthetic throat spray, this will be sprayed onto the back of your throat whilst you are sitting up. You will quickly notice a loss of sensation to your tongue and throat. The nurse looking after you will then ask you to lie on the trolley on your left side and will place a probe on your finger to monitor your oxygen levels. You will be given a small plastic mouth guard to put between your teeth to protect them during the gastroscopy. If you have dentures you will be asked to remove them first. If you have decided to have a sedative this will be injected into a vein and you will quickly become sleepy. A small suction tube, rather like the one used at the dentist, will be used to remove any saliva or other secretions produced by your mouth during the examination. The endoscopist will put the gastroscope into your mouth and ask you to swallow. The endoscopist will then push the gastroscope gently down your oesophagus into your stomach and on into your duodenum. You will be able to breathe normally through your nose. A small amount of air will be blown into your stomach to help the endoscopist to see clearly. This may be uncomfortable, but shouldn t cause any pain. 12

13 Flexible sigmoidoscopy When the gastroscopy is completed the nurse will reposition the trolley you are on, to proceed with the flexible sigmoidoscopy. The endoscopist will pass the sigmoidoscope gently into your back passage and will examine your bowel lining in your rectum and lower part of the bowel. The examination takes 5 to 15 minutes to complete. Some people experience slight discomfort within the left side of the abdomen as air is put into the bowel to enable the endoscopist to see clearly. If necessary, you can use Entonox gas to help with any discomfort. Polyp removal Occasionally the endoscopist may remove polyps during the flexible sigmoidoscopy. We may have already known about these or we may find them during the examination. A polyp is a protrusion from the lining of the bowel. Some polyps are attached to the bowel wall by a stalk and look like a mushroom, whereas others are flat without a stalk. If a polyp is found it is usually removed by the endoscopist, as it may grow and cause problems later. Polyps are removed using a high frequency electric current. Alternatively, the endoscopist may take some samples for further examination. After the examination We will ask you to rest for up to an hour if you have had sedation or Entonox. Your blood pressure, heart rate and breathing will be monitored. If you are diabetic, your blood glucose will also be monitored. Once you have recovered from the initial effects of any sedation you will be offered a drink and a biscuit. You should not have any pain other than some discomfort from wind, which will settle after a few hours. 13

14 Before you leave the department, a nurse or the endoscopist will explain the results of the examinations and whether you need any further appointments. If you haven t had a sedative you will be able to go home or back to work soon after the gastroscopy and flexible sigmoidoscopy. You will be given a copy of your endoscopy report. If you have had a sedative, it can make you forgetful and drowsy for up 24 hours after the examination. It is a good idea to have a member of your family or a friend with you when you are given the findings of your examination, just in case you don t remember everything we are telling you. If you live alone, we recommend that you arrange for someone to stay with you overnight. For 24 hours after the sedation you must not: drive take alcohol operate heavy machinery sign any legally binding documents. Most people feel perfectly back to normal after 24 hours. After you go home A sore throat and some windy discomfort is normal and will settle after a few hours. You may notice some blood next time you open your bowels, if a biopsy or polyp removal was carried out during the examination. If you have any problems with a persistent sore throat, worsening chest or abdominal pain or heavy bleeding during the next 48 hours, please contact: 14 John Radcliffe Hospital: Tel: Ask the switchboard to bleep Urgent Endoscopy Advice on 6825
